What the heck is it?

Just that. What's a brand name of the stuff that I will likely know about and be able to look for a generic to buy? I'm gonna check that I can find all the things needed for the stickied rodent feed mix, check prices, and then eventually do an experiment to see if it's all it's cracked up to be. I'm also curious about what "dried split peas and lentils, dried fruit and nut mix from Walmart" are about exactly.

Also, in says to feed what "you are eating". Specifically? (Besides what's listed).
